Not that I condone the replacement of the original power supplies with PC
supplies (I don't consider PC supplies any more reliable), but basically
your wall outlet supplies 15A at 110v (in the US anyway) which is 1650 watts
(P = VI). The power supply converts the 110v at 15A to 5v at 30A (don't know
if they really have 30A PC supplies or not), which is only 150 watts.

Since the two bulk supplies are having 8
H744's (25A versions) I was
just wondering about the feasebility of replacing them with standard
PC XT power supplies (just for the 5V), as the usually deliver also
between 25A and 30A, depending on the model. The large transformer in
the bulk supply will then be replaced with a smaller transformer to
deliver the LTC, DCLO, ACLO and +15V via the power monitor module
which is still there.
How can a normal PC XT power supply deliver 25-30A, when its plugged
into a normal 15A wall socket? Or is the amperage way different in
the UK?
